一般情況下,水資源的變化主要受氣候變化和人類活動的影響,但在位於我國西北內陸乾旱地區的中高山地帶,徑流的形成主要受前者的影響.甘肅省的河西內陸乾旱區是該省重要的工農業生產和經濟開發區,這里各項社會和經濟活動與出山徑流的變化都有著十分密切的關系.因此,筆者根據有關水文氣象臺站的降水、氣溫和徑流觀測資料,分析了以黑河、昌馬河、西營河等主要河流為代表的河西內陸區出山徑流的變化特徵與規律.結果表明,河西內陸區出山口徑流的季節變化主要受地理位置和河流補給來源的影響,而年際變幅則受山區降水量年際變化及變幅的影響十分明顯.目前,梨園河以西河流水量處于上升階段,梨園河以東的河流則處于下降的階段;以黑河幹流鶯落峽水文站年徑流為代表的走廊中部地區的出山口徑流正處於1990年開始的枯水段的上升段.但總體而言,河西內陸乾旱區出山口徑流的變化相對比較穩定.預計今後若干年內,河西內陸乾旱區東段河流出山口徑流的變化以偏枯為主,中段、西段河流出山口徑流的變化以平水或平水偏豐為主The analyzed results are as follows : the late 1960 ' s cutoff of riverbends increased both the runoff amount and the sediment transport amount of the lower reach of jingjiang river, while the sediment deposition decreased in the lkngting lake area ; after the mid 1980 ' s, both the middle reach of yangtze river main stem and the dongting lake occurred a trend of decreasing annual sediment transport as a result of decreasing sediment releasing from the upper reach of yangtze river ; and in the recent 3 years ( 2003 - 2006 ), the three gorges reservoir first impoundment additionally reduced the sediment concentration in the middle reach of yangtze river flow with a long time, so a distance would be quite long for suspended sediment recovery, but the distance for bed - material load of suspended sediment recovery would be quite short
分析結果表明: 20世紀60年代下荊江裁彎后,三口(松滋口、太平口、藕池口)分流分沙減少,下荊江徑流量和輸沙量相應增加,洞庭湖泥沙淤積減少; 80年代中期以後,長江中游幹流及洞庭湖出口的年輸沙量呈減少趨勢,城陵磯至武漢河段河床由淤積轉為趨向沖淤平衡;三峽工程初期蓄水運用后,長江中游含沙量沿程恢復距離較長,但床沙質部分恢復距離相對較短。Based on the analysis of satellite images of various periods, landform data and river channel transverse section evolution in the lower yellow river, the characteristics of the river channel boundary condition changes at different location are clarified as middle flood channel flood transport width and area are evidently decreased especially for the main channel with comparison to 1950s, beach area that is unimpeded before become blocked because of road, irrigation channel constructed on it, and consequently intensify high edge of beach and lowering dyke and river

摘要本文通過對近6年渭河下游水沙量數據的統計和分析得出,渭河下遊河段年內多沙期較河流主汛期有所提前;年徑流量和年輸沙量的變化趨勢基本一致,而且自60年代至2005年華縣站的水沙量持續呈遞減趨勢;河流的沖淤情況與該河段的降雨量有著直接的關系,當年平均降雨量小的時候河流以淤積為主,當年平均降雨量大的時候河流以沖蝕為主。分享友人
